Description
This dataset contains Normalized Difference Vegetation Index (NDVI) values extracted from Sentinel-2 imagery for areas around four major villages per fokontany. NDVI values were extracted within a 1 km buffer around each village, and an average weighted by the number of buildings per village was calculated for each measuring point.

🔹 Processing Steps
Processing and treatment of images using Sen2Chain : Download L1C (top of atmosphere) products from available suppliers / Processing of L1C to L2A (bottom of atmosphere) products / Calculation of cloud masks and radiometric indices; Calculation of NDVI using the following equation: (B08 - B4) / (B08 + B4) Extraction of NDVI values from Sentinel-2 imagery. Definition of a 1 km buffer around each major village. Calculation of a weighted average of NDVI values based on the number of buildings per village. https://espace-dev.frama.io/sen2chain/
